Everyone will go full digital in the future, it's inevitable. I see game stops closing shops all around my area (used to have 5, but now we only have 1).
No idea where you live but unless you want to exclude a huge part of gamers on this planet, digital will not be for everyone..especially at games with 100 and more Gigabytes. Not even in the US or Germany.
Those shops are most likely closing because of online stores anyway.
